Thank you very much.
You are the best teacher I have come across for signal and system sir. Thank you for the lectures.
These lectures capture each and every detail. Thank you alot for helping us out. Truely no one can teach signals and systems with this level of clarity. Amazing videos. Thanks alot.
hats off to this genius❤
Sir you have great knowledge about signal and system we are very thankful to u🙏🙏
Wonderful class sir❤🎉
Your teaching profession is very sharp and every point is clearily explain ❤️❤️❤️
One of the best lecture
Thank you so much sir for teaching this subject...your way of teaching is very nice
Very excellent way of teaching ❤

Dear students,
due to some unavoidable reasons, I am out of station for a week, we'll be continuing hopefully from first week of July.
Kindly cooperate.
Sir mai ne even gate academy ke signal and system ke previous video ko v dekhena band kr diye h ...kuy ki jo aap ne signal and system ka class diya h na ....use ke aage sub ka fail h way teaching .....thanks a lot sir ..
Sahi baat h
sandhya kumari baat me dam hai
neeraj raj We are waiting for your further lectures sir... Where are you sir?
Plz sir upload new more video lecture....we r wanting for u...plz sir

Big thank you
You are uniq person that I have ever seen.... ❤️❤️❤️❤️🙏🙏🙏🙏
good way of teaching
Thank sir ji providing deep information about this subject before it i afred of this subject
Sir I always make mistake in time variant,causal questions but because of you I have my concept clear.thank u sir.
Thankyou so much sir for such a nice lecture...🙏
Good after noon sir, i have see the all previous lecture in this module-1 and my doubt is clear, and i have also study the book is SIGNALS & SYSTEMS by P.Ramesh Babu,R Anandanatarajan and right now i am more confidence in this subject , So thank you very much .
Thanks for your valuable response dear,
May nature help you to achieve your goal at the earliest..👍👍
@@neerajrajspeaks9578 thank you sir
Aap great ho sir 💕💕i do not have the word how to praise you 😍
No one teacher teach like this...

Thank you sir ❤️
Niraj sir ..plz plz upload kijiye aage ka video lecture...kuy ki aap ne jaisa padhya h ake systematic way me waisa kahi v you tube pe ni h video leacture...plz sir upload your video as soon as possible sir..🙏🙏
Sir,you are so good. But,after completion of one sub-topic,if you solve past question papers related with that topic,then it will be the best. .
Muchas gracias ❤️...
Sir plz continue signal system..
sir!! 🙏 please upload videos of electrical engineering
Waiting for next lecture
Fabulous
Thanks Vishvesh for such high level of appreciation, will try my best to meet your expectations every time..👍👍👍
amazing sir
Sir please continue video lectures I am waiting sir
THANKS sir ji
Sir plz upload more lecture of signal ....we r wating for ur more video...
Sir please daily lecture upload kijiye
Thank you sir
Yes sir
Ye thoda complicated lecture rha mere liye
❤️❤️🙏🙏
waiting for the next lecture..sir please upload soon ....
Hello Rajeev,
Hope you have got the notifications properly and gone through the lectures till Z transform..
Thanks for your interest and believe..👍👍
Neeraj sir I request you plz continue video lectures series
Sir what is the difference absolute sum and discrete sum of DT signal?
thanku sir ...I m waiting for lecture 15 please upload it .
Hy
What are u studying
We are waiting u sir
Plz aap jldi aao n..
Plzzzzz
Sir where are u plz start sir...
@ 21:29 Time invariance
Thanks sir
Yes sir I want to full signal lecture .
Hello Amrish,
Hope you have gone through the lectures till Z transform.
Thanks for your trust and interest..👍👍
Sir next topic ka video kb upload hoyega sir....I am waiting for your lecture
But sir , why you skipped stability and vertibility Properties in this module
Sir
In the second example of time variant system :
y(t)=tx(t)
The time shift in output is equal to the time shift in input,
So it must be time invariant.
If u delay input by one unit den y1(t) =t x(t-1)....
And y(t-1)=(t-1) x(t-1)....
So time variant
Sir, can we say dynamic systems r anti causal...
Sir next lecture kab upload honge
Sir plz upload next part Sir and plz upload regularly
Increase the frequency of the lectures to 3 lectures per week
Hello sir,
I think so that July almost has been ended but next video doesn't reach on TH-cam.
Sir please tell us when nxt videos will come
sir kindly upload next video as soon as possible
sir, when will lecture 15 be uploaded?
Plz tell the another example like exponential like this
Upload next video I am waiting sir PLZZ upload module 2 video
Sir quality of camera is too low...even at 480p it doesn't seems clearly
Sir what about signal value at t=0 for causal non causal case
Thankyou sir
Sir next video kub upload hoja
y(t)=x(t)+4t time variant or not????
Baaaki 2 properties ka lecture kb aayega sir ji
Pdf nhi milta hai kya lec ka???
What is lnvertibility
Sir please pura signal system complete krva dijiye sir please
Nxt videos kab aayega
Better than rohit of made easy
Why r u nt uploading videos
Hello Bhagyashree,
Hope you have got the notifications of uploaded videos since last month.
Thanks for interest and faith..👍
Sir plzz I request u to not to break continuity I wait for Ur lecture
Hello Sukhdev,
We have maintained continuity since last month to reach up to Z transform, hope you have gone through the videos and getting notification properly..
Thanks for your support and trust..👍👍
Sir plz explain static and dynamic once sir
Present output depends on on future input means could you please explain clearly sir
sir can u give discreatev time signal exampe of nonlinear and linear and stability of system
y(t)=x(t-5)-x(3-t). This system is time variant or invariant? Please explain.
Hello Sultan,
I hv mentioned that for any system to be time invariant, there must not be any scaling in input.
In the part x(3-t) = x(-t+3), there is scaling ( you can consider time reversal as a special case of scaling with scaling factor=-1), so the system will be time variant..👍👍
@@neerajrajspeaks9578 Thank you sir for your response.
Sir basically I found this question in Gate tutor by Arihant. It is mentioned there that this system is time invariant.
The solution in book is : x(3-t+t0) = y(t-t0) and hence time invariant.
There must be any misprint I think, what else can I say?
It is variant.
Sum of k from -infinity to +infinity and functn is del(n-4k)-del(n-1-4k) .is that function periodic.if periodic then find the period
Bhagyashree Samantaray
substitute values of n from -infinity to + infinity and you will be having +ve and -ve impulses alternately separated by unit distance after each 4 unit distances, so the given sequence is periodic with N=4.
Sequence will be like
......{∆(n+4)-∆(n+3)} + {∆(n)-∆(n-1)} + {∆(n-4)-∆(n-5)}......
Thank u sir
@@neerajrajspeaks9578 sir in the solution which you have provided above do you mean to say substitute values of k from - infinity to + infinity?
By substituting values of k we get the time instances where the both our signals will exist and then we may subtract.
Dear sir,
Please resume our subject or at least tell us when you are going to upload next videos. It's been long we are waiting for you.
Sir plzzz upload the next module, I am waiting
Sir plz upload next video ..Mech engg ka module 5 start he ...Sir PLZZ upload module 2
